When RISC first came out nobody knew how to do pipelining with a CISC ISA. But a half decade and many engineering-years of effort later Intel was able to bring out a pipelined x86 processor. But it probably would have taken even longer with a CISCier ISA than x86 which lacks indirect loads and stores.
